Algebra.Com's Answer #149308 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! No matter how many leaflets you buy, you will pay at least £100. So that's why the constant cost of 100 is in there. Any leaflets you buy, you'll be paying 0.05 (or 5%) of a pound per leaflet. So this is why 0.05N is added. \r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Here are some examples:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you buy 100 leaflets, then N=100 and...\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "C = 100 + 0.05(100) = 100 + 5 = 105\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the total cost is £105\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Or if you buy 300 leaflets, then N=300 and...\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "C = 100 + 0.05(300) = 100 + 15 = 115\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the total cost is £115 \n" ); document.write( " |
